Introduction

Wenjie Che is an accomplished inventor based in Albuquerque, NM (US). She has made significant contributions to the field of cryptography and physical unclonable functions (PUFs). With a total of 2 patents, her work focuses on enhancing security and privacy in digital systems.

Latest Patents

Wenjie Che's latest patents include a "System and methods for entropy and statistical quality metrics in physical unclonable function generated bitstrings." This innovative approach proposes the Distribution Effect for the HELP PUF, which introduces biases in the mean and range parameters of path delay distributions to enhance entropy. The method fine-tunes a token's digitized path delays to maximize entropy and reproducibility in generated bitstrings.

Another notable patent is the "Privacy-preserving, mutual PUF-based authentication protocol." This protocol utilizes a Hardware-Embedded Delay PUF (HELP) to derive randomness from within-die path delay variations. It enables the development of an efficient authentication protocol that provides both privacy and mutual authentication, storing digitized timing values in a secure database instead of PUF response bitstrings.
